Wake-up call for boxelder bugs: Boisea trivittatus

 

 

Hordes of boxelder bugs gather on the outside of a home to enjoy a day in the sun – the perfect Spring Break for a boxelder bug! Bet you’re glad this isn’t your house!

Two weeks ago, we met a pesky home invader, the brown marmorated stink bug, as it stirred from its indoor redoubt and annoyed inhabitants of a home while attempting to escape outdoors to the natural world. As temperatures once again soared into the 70s, we turn our attention to reports of hordes of another rascal, boxelder bugs, festooning a suburban home. Boxelder bugs are members of the order Hemiptera, a.k.a. the “true bug” clan, characterized by their sucking mouthparts and gradual metamorphosis. Two years ago, a bug-friendly neighbor inquired about vast numbers of boxelder bugs aggregating on their patio and the sunny side of their house. As our friends opened and closed doors, these rascals snuck inside for reasons known only to themselves and Mother Nature. Last week, a family member in eastern Pennsylvania sent images of dozens of boxelder bugs lounging on the side of their house. How did these rascals arrive and why are they now active?

Ok, boxelder bugs are a little creepy when you see hordes of them on the side of the house or the tool shed. (private)

Here’s the story. Depending on geographic location, boxelder bugs complete one to three generations each year. They survive winter’s ravages hiding in cracks and crevices beneath shutters and under siding, and by entering other access points in structures. In natural settings outdoors, winter refuges include loose bark or hollows of trees, tangles of brush, and voids under rocks. During the last few weeks as temperatures soared into the upper 60s and 70s here in the Washington metropolitan region, boxelder bugs emerged from these redoubts and made their presence known inside homes as they sought a way out. On the exterior of homes, they aggregated in large numbers to soak up thermal energy from the sun. Spring and summer are times for foraging on a wide variety of plants, including seeds of their namesake tree, boxelder, as well as other members of the maple clan. Both adults and nymphs feed on propagules of many different kinds of seed-bearing trees and on the juicy tissues of many other landscape plants.

Seeds from this old maple tree support a population of boxelder bugs that sun themselves on the side of a home on warm spring days. Wanderers sometimes enter homes, creating a nuisance. Others battle as they feed on a maple seed on the ground. Males and females pair off, and after mating females deposit eggs in many places, including sides of buildings. Wingless nymphs that hatch from eggs feed on a wide variety of plants.

After gaining sufficient nutrients, mated females deposit eggs on a wide variety of substrates on the ground and also on human-made structures. In autumn, large clusters of boxelder bugs gather on trees and buildings where they become a nuisance. In the waning days of autumn, they seek winter shelter. They enter homes through cracks in the foundation, gaps in siding around windows or vents, and beneath doors and windows. On cold winter days they are inactive, but as winter retreats and temperatures warm, restless boxelder bugs move about and make their presence known inside and out.

Boxelder bugs are not harmful to humans or pets. They do not bite, sting, or reproduce indoors, however, if you squash them on your drapes or walls, they will stain. So, don’t do that.

To limit the number of boxelder bugs taking up residence in your residence, eliminate overwintering places such as piles of lumber, fallen branches, or other refuges close to the house. Some folks go as far as removing boxelders, other maples, and ash trees from their landscapes to reduce food sources for nymphs and adults. Weatherproofing your home can also help keep these invaders out. Caulk and seal openings where utilities enter the home. Repair or replace door sweeps and seal any openings around windows, doors, or window air conditioners.

If you find them inside your home, you might try this. Simply get out the hand-held vacuum, suck them up, and release them back into the wild. It is wise to choose a liberation point some distance away from your home.

The boxelder bug’s clever mouthparts (proboscis) enable it to feed on seed and plant tissues.

Spring has almost sprung, and with it comes the emergence of many common household pests. As a new homeowner, your excitement over your new beginning and all the possibilities your property offers could quickly be overshadowed by a pest infestation.  

All too often, pest control is used as a reactive tool to treat infestations once a problem becomes obvious. However, preventive services, routine maintenance, and a new home pest inspection are more valuable approaches than many new homebuyers realize.  

Your new home is one of your greatest investments. Let’s explore ways you can proactively manage common spring pest issues throughout the region, which sees its fair share of pests all year long. With more than four decades of experience serving Massachusetts, Connecticut, Rhode Island, and New Hampshire, Catseye Pest Control understands what you’re facing. Learning how to deal with pests from the beginning can save you both stress and money later.  

Inspect Your Property Before Spring 

Getting started ahead of the season can help ward off potential problems before they begin. Ideally, you want to arrange a new home pest inspection before you close on your new home. Beyond the standard home inspection, this essential step can make all the difference in making sure your experience as a homeowner goes as smoothly as possible.  

Pest control professionals will look for the presence of potentially catastrophic pest infestations, including termites. These wood-chewing, destructive pests create billions of dollars in damage to properties annually. Homeowners insurance policies typically don’t cover that type of damage, which is why getting a pest inspection is so critical. 

Proactive Seasonal Pest Control 

Once the deal is done and you have closed on your home, your pest journey isn’t over. Although pests of all types are active year-round, many begin emerging as New England’s weather starts warming up in spring. That’s why a spring inspection is particularly helpful for both new and established homeowners.  

Performing a rigorous visual inspection, indoors and outside, can help you spot potential entry points and signs of a possible infestation.  

Look for: 

• Gaps and cracks in the foundation 
• Openings in siding joints and around utility lines 
• Gaps under doors or around windows as well as broken screens 
• Exposed vent openings, which can be covered by wire mesh or a similar barrier 

Clean and Declutter 

Inspecting your property is an excellent starting point. It will give you a lot of valuable information and help you become familiar with your new home. Beyond performing an inspection, cleaning and decluttering is another powerful preventive strategy. It seems simple, but it can be challenging when you’re in the middle of a move. The more you can do to remove potential sources of food and shelter for pests, the more you can reduce your chance of an infestation.  

Kitchen 

The kitchen can be like a “welcome” sign to unwanted pests. Food, including pantry goods, can attract hungry scavengers in search of their next meal. Likewise, dirty dishes, crumbs on counters and flooring, and even exposed pet food can attract pests of all sorts.  

• Store all food, including pet food, in rigid, airtight containers.  
• Regularly remove the trash and keep it in tightly lidded containers. 
• Routinely wipe down counters, appliances, and stovetops. 

Remove Clutter 

Pests seek hidden, out of the way places to hide and nest. Clutter offers ample shelter and can disguise pest activity for weeks, months, or even longer. Go through moving boxes promptly and remove them to avoid attracting and harboring pests. Eliminate overcrowded cabinets, piles of clothing, and stacks of paper. Taking time to eliminate clutter now can save you a lot of headaches and hassle later.  

Vacuum Regularly 

Vacuuming is an underrated pest prevention strategy. Not only will vacuuming remove dust, dirt, and pest-attracting food particles, but it will also reduce the amount of pet hair and lint that can attract fabric-loving pests like carpet beetles. Additionally, vacuuming can remove pests, including mites, stink bugs, and millipedes, along with shed skin and egg casings. This will provide a start on treatment if it’s needed and eliminate debris to make pest control treatments more effective once they are applied. 

Secure Your Outdoor Space 

Your indoor space is important, but the great outdoors also plays a critical role in your new home’s defense against pests. Getting rid of outdoor clutter is a critical step. Sealing any gaps, cracks, or openings that provide pests with an “in” is equally essential. Depending on how prone your new home is to pests, rodents, and wildlife intruders, you might consider investing in a permanent solution like Cat-Guard Exclusion Systems. These long-term barriers offer chemical free, humane protection that keeps pests out.  

Trim Vegetation 

Trimming trees and shrubs will help keep your plants healthy. It also helps ensure that limbs remain a minimum of six feet away from your home’s exterior walls. By doing this, you can reduce the odds of many pests, including rodents, trying to scamper into your new home. Likewise, keeping the lawn regularly mowed will make it less of a shelter for ticks and other pests who would hang out in tall grasses.  

Clean Gutters 

Clogged gutters provide a prime breeding ground for many pests, including mosquitoes. Additionally, gutters can offer shelter to other pests, including rodents and birds. Keeping gutters clean and free-flowing helps reduce the risk. It also ensures your gutters work properly, which further protects your home’s structural integrity. 

Store Firewood Away 

You might be surprised by the number of insects and other pests that your firewood could be harboring, including wood boring beetles, carpenter ants, spiders, and rodents. To minimize the risk of these pests finding their way into your home, store firewood at least three to five feet from the outside of your home. 

Inspect and Repair Screens 

There’s nothing like getting a little fresh spring air into your home. Unfortunately, if your windows or door screens aren’t intact, you could inadvertently invite flies, mosquitoes, and other nuisances to come inside. 

Schedule Professional Pest Control 

As a new homeowner, one of the best things you can do for yourself is rely on trusted professionals. Effective pest control and prevention isn’t entirely a DIY proposition. Experts like Catseye’s trained, licensed technicians know exactly what to look for and can offer valuable advice about the preventive steps you can take. Additionally, you can opt for targeted services like pest control for bees, wasps, and hornets to keep your outdoor spaces pest-free.  

Be Mindful of Common Wildlife 

Wildlife viewing can be great fun — unless that wildlife is lounging around under your roof. The region is home to many species of wildlife, including bats, mice, rats, squirrels, skunks, and groundhogs that can wreak havoc both inside and out. Some wildlife will damage structures and gnaw on wires. Others may pose a health risk and spread dangerous germs. Keeping your home and outdoor spaces clean and sanitized and storing trash in wildlife-proof receptacles can help reduce nuisance wildlife.  

Practice Responsible Gardening 

Additionally, it’s helpful to keep debris, mulch, and wood chips away from your home and frequently enjoyed outdoor spaces. It’s natural to be excited about all you can do with your new outdoor spaces, but keep in mind that your gardening approach can help or hinder your pest prevention plan. For example, overcrowding your plant beds may add a lush look, but it also offers easy shelter for rats and other pests. You might also consider incorporating some pest-repelling plants in the design. For example, lavender and citronella grass repels mosquitoes and other insects.

We visited plasterer bees in the spring of 2020 at the onset of the Covid epidemic. Let’s go back in time to that earlier episode and see how these spring beauties roll.   

April 13, 2020 – “Fortunately, before the shelter-at-home orders kicked into high gear, I was able to visit a park and vacant golf course to piece together more details about these fascinating ground-dwelling bees known as plasterer bees. Along with beetles, flies, and butterflies, bees are among the premier pollinators on the planet. Plasterer bees are some of the very first native pollinators to appear each spring. The name plasterer stems from their intriguing behavior of building galleries in the ground and then coating the interior surface of their burrow with a thin, glossy, translucent material produced by a gland in their abdomen. Plasterer bees use their tiny mouthparts to remove the soil when constructing their galleries. The excavation is accompanied by a buzzing sound that may help loosen particles of soil and aid in the digging process. The bee’s mouthparts are also used like a mason’s trowel to spread the glandular secretion on the inside of the burrow before it dries into a cellophane-like coating. How clever! This habit of sealing their galleries gives this bee the common name plasterer bee.

What’s up with all these holes in the ground? Watch, listen, and learn a little bit about the fascinating lives of plasterer bees.

Plasterer bees are relatives of honey bees and bumble bees but, unlike their cousins, these bees are solitary. Rather than living in a communal nest, each female plasterer bee constructs a subterranean gallery of her own to serve as a home for her brood. Burrows are provisioned with a semi-liquid concoction of nectar and pollen from flowering plants that bloom early in the spring. This yummy delight is food for bee larvae that develop during the summer and fall within the galleries. Although they are not considered social insects, large numbers of plasterer bee galleries are often abundant in close proximity in sandy soils with thin vegetation.”  

While exploring nesting sites along Disc Golf Course in Patapsco State Park last week, I was delighted to see dozens of small plasterer bees zooming inches above the ground. While swarming bees at the margin of fairways might dismay some disc golfers, bee dread is unwarranted. Unlike yellow jackets, baldfaced hornets, and other stinging terrors, plasterer bees are docile and extremely reluctant to sting. Remember, each female bee is a mother and to risk her life by stinging a human could mean instant curtailment of her reproductive potential should she die in the encounter. Over large areas of a balding zone in the rough, several burrows could be found in each square meter of ground. The plasterer bees were not responsible for the balding turf. They simply colonize areas where the turf is naturally thin. If you see swarms of small hairy or metallic colored bees constructing burrows or emerging from galleries in your garden or lawn, please resist the urge to treat them with insecticides. Several species of native pollinators, including anthophorid bees, yellow-faced bees, andrenid bees, halictid bees, as well as plasterer bees nest in the ground. Enjoy these beauties and give them a break. They pollinate plants and keep our planet humming.  

On a warm afternoon last week plasterer bees swarmed over the surface of a sun-drenched embankment along the Patuxent River. Excavations by hundreds of plasterer bees created tiny volcanoes of brick red soil along the slope. While some bees buzzed about, others were busy constructing burrows or dashing off to bring provisions back to their subterranean galleries.

Some people refer to pests as a silent threat, which isn’t all that far off the mark. Many pests make little to no noise and can remain hidden even while causing destruction and potentially spreading contamination throughout a commercial or industrial property. For businesses, pests pose multiple risks. From endangering public health to impacting the business’ reputation, the perils of not maintaining a pest-free environment are substantial. 

Let’s explore why commercial pest inspection is so vital at this time of year.  

Importance of Early Spring Pest Inspections 

Commercial pest inspections and pest control are important year-round. However, many pests become less active in winter and then emerge in droves as the weather warms up. Spring is also prime mating season for many pests. Depending on how mild the winter season is, pest activity can start earlier than you may think.  

The costs of an infestation can be tremendous. Not only can it increase operating costs, but an infestation can also lead to lost revenue, a floundering business reputation, and lower staff morale. 

Prevention Is Better Than Cure 

Commercial pest inspections uncover any signs of pest activity. By scheduling inspections in the early spring, businesses can get a jumpstart on their pest control strategies and maximize them. Better yet, this practice allows you to catch infestations early. Preventing pests or nipping them in the bud quickly helps minimize potential damage to the property and the business itself. Research shows that a proactive approach is the key to minimizing business disruptions.  

Protection for Your Health 

Rodents and insects such as cockroaches and ticks can carry disease-causing pathogens, including E. coli and salmonella. Scampering around in a commercial property, pests can easily spread contaminants that could lead to serious illnesses like food poisoning, hantavirus, and leptospirosis. One of the most common pests, flies can spread serious illnesses like cholera and dysentery. Optimal pest control eliminates the risks, protecting your health and the health of your employees, clients, and customers.  

Preservation of Your Property 

Many pests, including rodents and insects like powderpost beetles and termites, can cause significant property damage. Rodents often squeeze through small openings and gnaw their way through many types of materials, including wood. Carpenter ants tunnel through wood, creating a mess that weakens a building’s overall structure. To maintain the structural integrity of the commercial property and protect electrical equipment from damage, pest prevention is a must.  

Seasonal Pest Cycles 

It’s not uncommon to see an ebb and flow in the population of some pests, depending on the season. For example, many people report an uptick in rodent activity in fall and winter, when mice and rats seek shelter from cold temperatures. In spring, many business owners report an increase in termites, carpenter ants, stinging insects, and cockroaches.  

Eco-Friendly Pest Control 

Working with professionals, you can rest easy knowing that the pest control measures in use are safe and effective, with a minimal impact on the environment. For example, at Catseye, we offer the most innovative treatments and operate with client safety and well-being top-of-mind. Additionally, we also can provide chemical-free, humane Cat-Guard Exclusion Systems, which are permanent barriers that eliminate pests’ ability to enter the property.  

Peace of Mind 

Business owners have enough to worry about without adding pests to the list. By tackling the pest inspection in early spring, it’s possible to get ahead of potential problems before they even begin. Plus, getting advice from experts about additional preventive measures can provide a lot of assurance. Knowing the property has a clean bill of health and is pest-free will allow you to focus on the business at hand.  

Professional Expertise 

Professionals can get to the root of the problem, ensuring safe, effective prevention and elimination of infestations. The technicians inspecting the property have a highly trained eye and know exactly what to watch out for when the most minute details matter. 

In addition to removing rodents and nuisance wildlife and administering treatments to get rid of insects, the technicians at Catseye also handle commercial disinfection services. This allows us to make sure all traces of the infestation are gone, and all surfaces are cleaned and properly sanitized.

With our planet reaching the unenviable landmark of experiencing the warmest February on record and the warmest 12-month period in history, March temperatures keep marching right along with more projected highs near 70. As predicted, record warmth in temperate zones like the DMV means that insect activity will begin earlier and extend later each year than it has in years past. Not only will the action start earlier outdoors, but insects that have overwintered in our homes will be on the move earlier as refuges in attics and various nooks and crannies around our homes heat up. With temperatures now in the mid to upper 60s, home invaders like stink bugs are on the move in homes and offices, accumulating on windowsills, walls, and doors and buzzing about indoor lights at night. Why all the activity at this time of year?

The answer lies in the age-old pattern of life crafted by stink bugs to survive the ravages of winter and emerge just in time to take advantage of bountiful leaves and fruit found on plants in the spring. Millions of folks throughout the nation were treated to invasions of stink bugs last autumn as the horde sought refuge in homes, schools, and office buildings. Many people mistakenly believe that stink bugs enter buildings in winter to ‘get warm’, but this is not the case. In the natural realm where stink bugs evolved over millions of years, stink bugs sought winter refuge in sheltered spots beneath the bark of trees or in rocky crags. Protected from the onslaught of winter, stink bugs chilled out and entered a season of inactivity akin to hibernation where they awaited the return of favorable temperatures and springtime food. Lengthening days and warming temperatures signaled the return of leaves, flowers, and fruit. With the return of food sources, stink bugs answered Mother Nature’s wake-up call and moved from their refuges to the greening landscape. During the past week with warm weather, flowers, leaves, and yes, pollen, exploded on trees, shrubs, and herbaceous plants in the Washington metropolitan region. Inside attics or beneath the siding on homes, these warm days have convinced stink bugs that spring has arrived and that it is time to return to the wild to seek food and pursue the biological imperative of finding mates and laying eggs. On warmish days this winter, every now and then I collected a stink bug or two wandering about the kitchen or living room. But as of this week, these occasional sightings have turned into a steady stream and I collect stinkers daily.

As you deal with stink bugs this spring, here are some things to consider. Recently, I was asked if “stink bugs breed in my home?” To the best of our knowledge, the answer to this question is no. In the normal course of events, stink bugs move from winter refuges to plants outdoors where they feed for several weeks before they become competent to lay eggs. In your attic or an unused bedroom there is simply no food to provide the sustenance needed by stink bugs to produce eggs. Even if a stink bug laid eggs indoors on a windowsill or wall, there would be nothing to sustain the young bugs, which require plant food for growth and development. Having made this claim, I might back-peddle just a little, as we have received reports of stink bugs feeding on house plants such as orchids and potted ponytail palms. Will stink bugs lay eggs on houseplants indoors? One homeowner discovered a batch of stink bug eggs on a houseplant in the spring a few years ago. So, the final answer to this jeopardy question is yes, they might breed in your home. The chances of stink bugs sustaining a population in your home probably lies somewhere between zero and nil, unless you have bountiful fruit bearing plants in your home and do everything to ignore stink bugs dashing about on those plants.

Another question that always comes up is “what should I do about stink bugs that appear in my home this spring?” Sweeping, vacuuming, or simply picking them up and disposing of them is still our recommendation for control indoors. Because they will be active for a relatively long period of time, we are not recommending the application of insecticides to indoor living spaces to control stink bugs as they appear. Exposure of children and pets to pesticides could be worse than exposure of children and pets to stink bugs. In fact, many pets and some children will be amused by a few stink bugs wandering about.

As daytime temperatures warm in spring, stink bugs that invade homes in autumn try to escape to the world outdoors. Whether they are meandering across a mantle, grooming on a coffee mug, dashing up a storm door, or visiting the beach on a screen saver, stink bugs are on the move.

Will stink bugs be as problematic this year as they were in the watershed years of 2010 and 2012? Probably not. Although stink bugs have now spread to 47 states and 4 Canadian provinces, in our region most people agree that fewer stink bugs plagued gardens, homes, and farms recently than they did several years ago. Fascinating studies suggest that a combination of climatic events and Mother Nature’s Hit Squad of predators, parasitoids, parasites, and pathogens have conspired to smack down populations of stink bugs. Scientists at Virginia Tech found that rapidly plunging temperatures associated with weather phenomena such as the polar vortex may reduce survival of overwintering stink bugs. Studies conducted at the University of Maryland revealed that young stink bugs thrive only when the proper complement of microbes are present in their gut. These microbes pass from mother to offspring when youngsters consume exudates smeared on the surface of their eggs by their mother. Without this complement of microbes, survival and development of stink bugs is reduced. Authors suggest that high temperatures may harm this microbiome and thereby reduce colonization by stink bugs. Maybe our record warmth does some good after all.

With respect to Mother Nature’s Hit Squad, in previous episodes of Bug of the Week, we met vicious predators such as the Chinese Mantis, Wheel Bug, and Black and Yellow Garden Spider as these feasted on stink bugs. Scientists at the USDA found several species of indigenous predators such as ground beetles and katydids attacking eggs of stink bugs in orchards and vegetable crops. Researchers at the University of Maryland discovered several species of tiny native wasps metering out significant mortality on eggs of stink bugs in ornamental plant nurseries. And yes, stink bugs are susceptible to pathogens as well. Scientists at Cornell have described a tiny microsporidian parasite called Nosema maddoxi infecting several populations of stink bugs around the nation. Collectively, weather events and natural enemies are helping humans to win the war on one of the most serious recent invaders to arrive in our country.

Spring! This magical season is marked by warming temperatures, greener scenery, and blooming plants. After the long, cold winter, spring makes us feel like the world is waking back up in an appealing way.  

If you’re like many people in the Northeastern United States, the thought of spring is like a breath of fresh air. Unfortunately, for some people, it can also be the beginning of a season filled with coughing, sneezing, and sniffling due to seasonal allergies. As the world begins to bloom, people spend more time outdoors. At the same time, many pests begin reemerging and becoming more active.  

Allergy season kicks off in the spring, affecting more than 20 million people in the U.S. This year, Catseye Pest Control wants you to feel more in control of your allergies, starting with understanding how allergies and spring pests are connected.  

Allergies and Springtime Pests 

More than one in four Americans suffers from allergies, with 25.7% of adults reporting seasonal allergies to the U.S. Centers for Disease Control and Prevention. Most people associate allergies with pollen from trees and flowers. However, another, lesser-known allergy trigger can be a problem — the connection between allergies and the pests that emerge as spring begins to bloom.  

Although some allergy triggers, like pollen, for example, aren’t within your control, allergies triggered by pests can be avoided with preventive services and routine treatments. Some measures, such as permanently closing entry points with Cat-Guard Exclusion Systems, which are rigid, chemical-free barriers, can provide long-term, year-round solutions.  

Pollen and Allergies 

Have you ever stepped outside and noticed your car or other surfaces coated in a light, powdery, yellowish substance? That’s pollen. These tiny, fine grains are generated by plants to pollinate and fertilize the species and create seeds. The pollen from weeds, grasses, and trees is very dry and light, making it easy to disperse in the wind. 

That makes it easy for pollen to spread in the wind and find its way into your eyes and respiratory system. For those with pollen allergies, pollen triggers allergic rhinitis. In spring, pollen comes primarily from trees and grasses, with weeds producing pollen from late summer through autumn. 

Insects and Allergies 

Pollen isn’t the only contributor to spring allergies. As biting and stinging insects like mosquitoes, bees, and ticks become more active, there is usually an uptick in allergic reactions. Household insects, including cockroaches, can trigger many symptoms that mirror pollen-borne allergies. These symptoms may include itchy, watery eyes, sinus inflammation, nasal congestion, coughing, and wheezing.  

For anyone sensitive to common household insects, contact with their saliva, shed skin and body parts, and droppings can trigger an allergic response. 

Dust Mites and Allergies 

Dust is common in homes and businesses alike. Dust mites are tiny insects that are closely related to spiders and ticks and live in dust. They eat dead skin cells and typically thrive in warm areas like bedding and carpeting. The shells and droppings of dust mites contain enzymes that can trigger symptoms like runny noses, sneezing, coughing, and wheezing. 

Mold and Allergies 

Mold can pose a real household danger. For those with mold allergies, breathing in the tiny spores causes an immune response that often leads to coughing, itchy eyes, postnasal drip, congestion, and skin irritation. Mold exposure can also trigger asthma attacks and lead to other airway problems, including breathing restrictions. 

Rodents and Allergies 

The dander, hair, and proteins in rodents’ urine can trigger allergic responses and asthma attacks. Although you may think that dander and hair are the primary offenders, the protein in rodent urine is the biggest allergic trigger. Up to 33% of people who encounter rodents frequently develop allergies to them, according to data from Ohio State University College of Veterinary Medicine. Additionally, rodents can bring other allergy-inducing pests indoors with them, including mites and ticks.  

The Role of Professional Pest Control Services for Allergy Reduction 

Now, you can see how allergies and spring pests go hand-in-hand. Reducing exposure to common allergy triggers, including dust mites, cockroaches, rodents, and other insects, is essential. Professional pest control provides an effective environmental control strategy. An integrated pest management (IPM) approach combining the strategic use of pesticides, cleaning and sanitization, and preventive measures can also help effectively reduce allergen levels. 

Contact Catseye Today for a Sneeze-Free Season 

As the snow melts away and flowers start to bloom, many people eagerly await the arrival of spring. If you find yourself dreading the beginning of seasonal allergies, there are proactive steps you can take to mitigate the risks. We may not be able to reduce the pollen count, but Catseye can provide comprehensive preventive services to keep allergy-triggering pests under control.

As our lingering El Niño keeps local bugs in suspended animation, Bug of the Week makes a stop in Costa Rica before returning to Borneo where we recently visited scary potter wasps, stridulating longhorn beetles, fierce arboreal and terrestrial ants, stingless bees, giant millipedes, and pretty lanternflies.  This week we meet beautiful Marpesia butterflies on a Pacific beach and pretty Cepora butterflies along a riverbank in Gunung Mulu National Park. These gorgeous butterflies engaged in a poorly understood behavior called “pumping.” No, this is not the kind of pumping Arnold Schwarzenegger or Hans and Franz of SNL made famous with heavy weights and muscular contortions. In previous episodes we met temperate swallowtail butterflies feeding on unusual substrates including carcasses of fish and piles of dung to obtain vital minerals and nutrients not found in nectar of more traditional hosts like the blossoms of flowers.

Butterflies frequently “puddle” in muddy soil using their proboscis to gather dissolved elements from moist mineral laden earth. “Pumping” is different. This infrequently observed behavior occurs when a butterfly rapidly imbibes water with its soda-straw-like mouthparts and rapidly expels it from the rear end. In 1963 Walfried Reinthal made the following observations of a swallowtail butterfly pumping at the edge of a swimming pool: “This pumping in of the water through the proboscis and at the same time eliminating it from intestines went on uninterruptedly for about the next twenty minutes. During this interim over two hundred and fifty drops of water were counted …” At a loss to fully explain this behavior Reinthal suggested that perhaps “the insect had to give itself a sort of internal lavage…”  Other observations of pumping include those of Eduardo Welling who witnessed a swarm of about 30 swallowtail butterflies pumping in a “stinking hollow of mud” near a lagoon in Quintana Roo. He wondered if the behavior was related to the excessive heat and humidity of the tropical day.

Watch as a lovely Marpesia sips water from the sand and expels droplets from its abdomen about once every five seconds. An equally lovely Cepora drinks along a rainforest riverbank and shoots water out its derrière. This poorly understood behavior in butterflies is called pumping.  

Butterflies have many mechanisms to warm and cool themselves, the business of thermoregulation. Basking in the sun, avoiding conductive heat loss in the wind, and shivering are all used by butterflies to warm themselves. Respiratory cooling by evaporation and shade seeking are mechanisms used by butterflies to chill out on a hot day. In his treatise on thermoregulation in butterflies, Harry Clench suggested that pumping might be a way for a butterfly to rapidly warm or cool itself depending on the differential between ambient air temperature and the temperature of the water being pumped from the soil. Although I find the notion of butterflies performing self-lavage odd and intriguing, hey, in the world of insects stranger things have happened. Watching beautiful Marpesia and Cepora expelling droplets of water is a strange and intriguing site to behold irrespective of the reason.

Insulation is more powerful than you may realize. Not only does it help keep your home warmer in winter and cooler in summer, but it can save you money on energy costs and protect your property from pests. Despite the many benefits, however, roughly 90% of homes are under-insulated, according to data from the Insulation Institute.  

Insulation is often one of the areas that insects, rodents, and wildlife such as squirrels and raccoons focus on for making their nests. In addition to contaminating the materials, pests can also damage insulation and lower its effectiveness.  

Let’s take a closer look at the insulation and pest control connection. 

Understanding the Winter Rodent Problem 

Rodents don’t hibernate, but they don’t like the cold, snowy conditions associated with winter. Once temperatures start dipping, mice and rats begin looking for warm, safe spots to shelter throughout the cold season. That’s why so many homeowners see an increase in rodent activity in winter months.  

Rodents are typically attracted to areas like wall cavities, underflooring, and attics, all areas that typically contain insulation. Additionally, thermal insulation is often made of materials that are soft and flexible as well as brittle and chewable, making the insulation materials ideal for nesting. 

Once rodents start chewing on or nesting in insulation, it can attract more rodents to the area. With a growing rodent population, the risk of contamination from rodent-borne diseases like hantavirus also increases. When rodents nest in insulation, it also degrades the materials and makes them less effective. In turn, your home will have more difficulty withstanding the frosty temperatures, which increases your home’s energy use. 

Insulation’s Role in Pest and Rodent Prevention 

Consider insulation as a crucial component in maintaining a home’s integrity, rather than a pest barrier. Insulation plays a significant role in moderating a home’s internal climate, which indirectly influences pest activity. For instance, a well-insulated and ventilated attic space is key to creating conditions that are less attractive to insects. This is achieved by reducing moisture levels and regulating temperatures, factors that can help deter pest habitation.  

Various insulation types contribute differently to this environment. Batt insulation, which may include reflective or paper facings, and blown-in insulation, although not pest-proof, can support these goals when part of a comprehensive approach that includes proper ventilation. This strategy helps to establish an attic environment that is less inviting to pests by addressing the underlying conditions that attract them, such as excessive moisture and unregulated temperatures. However, it’s important to recognize that replacing insulation alone does not solve pest issues, as pests like mice often nest within insulation and insects may reside beneath it, highlighting the need for a holistic pest management strategy. 

Closing Entry Points 

Gaps, cracks, and other tiny openings in the foundation, roof, soffits, and areas around doors, windows, and pipes may not seem like a big problem, but insects and rodents can exploit these areas to get into your home. Rats can squeeze into openings as small as a quarter, and mice can fit through gaps as small as a dime. That underscores just how important it is to close off entry points, a task that proper insulation effectively accomplishes.  

Maintaining Warmth 

Insulation helps keep your home warmer in winter and cooler in summer by slowing or reducing heat transfer. You will see this expressed as the insulation’s R-value, which measures the materials’ ability to resist heat flow. The higher the R-value, the better the insulation’s thermal performance. In turn, it helps even temperatures while reducing energy use to maintain the desired level of warmth. 

Noise Dampening 

Another benefit of insulation is its ability to muffle noises, both from the outside and from room to room. Some materials offer more noise reduction than others. For example, cellulose and spray foam offer excellent noise reduction, while rolled fiberglass is another good option.  

Prevention Is Key 

Keeping insulation intact and working effectively will keep your home environment more comfortable and help prevent pest activity. To accomplish that goal, proactive measures are essential.  

Seal Cracks and Gaps 

While insulation itself can help seal off entry points, it’s important to inspect all areas to seal additional openings. Doing so will help decrease air flow and reduce drafts, while keeping critters like rodents and insects from entering your home. Adding caulking and weatherstripping around doors and windows and sealing the areas behind outlets and switch plates as well as where wiring, ducting, and plumbing enter walls can make a significant difference. 

Choose the Right Insulation 

Just like pest control measures, insulation isn’t a one-size-fits-all proposition. Working with professionals is essential for choosing the right types of insulation materials that meet recommended R-values. Additionally, each area where insulation is installed can impact the types of materials you choose. Blankets, batt, and blown-in materials are excellent options for existing wall cavities, floors, and ceilings. Spray foam is another excellent option that is particularly well-suited to new wall cavities and unfinished attic floors.

This week we return to Borneo and to a lodge on the banks of the Kinabatangan River where a vendor set up a small table of their wares. Amongst the colorful trinkets, a large potter wasp decided to set up shop and build a series of clay pots which would be the nurseries for her offspring. Nests are often built on sunny exposed structures such as on tree trunks, rocks, or buildings, but in this case a somewhat shaded display table worked just fine. After finding just the right blend of muddy clay soil near the riverbank, the female wasp gathers it into a ball and transports it to the nest site. Using mouthparts and legs, the clay is molded into to an oblong pot cemented to the underlying substrate.

While the pot is still unsealed, mom lays an egg inside the pot, attached to the clay by a silken strand. She then goes into the forest to hunt caterpillars, the larvae of moths and butterflies. Hapless caterpillars are stung and paralyzed but not killed by the venom. Immobilized and defenseless, the caterpillars become a stable source of fresh meat for the developing wasp larva. Once captured by the wasp, the hapless caterpillars are carried back to her nest and stuffed into the pot. Often several different species of caterpillars will be used as a food source. In one study the number of caterpillars found in each chamber ranged from 4 to 9.

This small table of trinkets holds a surprise, the nest of a potter wasp. Watch as she crafts a clay pot and then flies off to find a caterpillar that will serve as food for her young. She stings the caterpillar with paralytic venom and stuffs it into the pot which already contains her egg. The caterpillar is fresh meat for her spawn. The pot is sealed with a glob of mud and after a drink of water, off she goes to hunt for mud and caterpillars to start the next pot.

With sufficient food available for her baby to develop, the pot is sealed with another glob of mud and construction of the next pot begins. Each pot in the nest requires no more than a day to build and provision. Individual pots are added to existing ones and some potter wasp condos may consist of more than 20 individual chambers with growing wasp larvae inside. The entire multi-pot construct is then sealed with a layer of mud to help thwart predators and parasitoids intent on making a meal of paralyzed caterpillars and developing wasp larvae.

This Bornean potter wasp is part of a large widely distributed clan of more than 3,000 wasps known as the Eumeninae. In a previous episode, we met pretty potter wasps in the genus Ancistrocerus in Maryland where we commonly see adults feeding on the nectar and pollen of goldenrods in autumn.

Rhode Island winters are notorious for their large amounts of snow, icy conditions, and extended periods of frigid temperatures. Although you might assume that those conditions keep pests at bay, winter can be a very active time for many of the state’s most common pests. Learning about the types of pests to watch out for along with how to watch for signs of pest activity and what to do if you suspect a pest are essential components in home protection.  

Common Winter Pests in Rhode Island 

People like to cuddle up with each other and get cozy during the cold weather months. Unfortunately, that is also true for many pests, which drives them to move indoors and find a warm place to call home. Let’s take a look at six common winter pests in Rhode Island, along with tips from the experts at Catseye Pest Control for preventing infestations. 

Rodents 

Rodent infestations may be one of the top complaints that many pest control companies get during winter, including house mice, deer mice, field mice, and rats. Rodent activity seemingly surges during winter because mice and rats move indoors for warmth and shelter. Both types of animals can squeeze through tiny openings to nest inside walls, attics, and even under appliances. These critters are a health hazard that can contaminate food and surfaces with pathogens that cause diseases like hantavirus and salmonella. Rodents also commonly chew through wiring, insulation, and structural elements.  

Rodent Prevention Tips 

Maintaining sanitary conditions and eliminating easy food sources for rodents is an excellent starting point for preventing rodent infestations. Top tips include: 

• Store food in airtight containers made of rigid plastic, glass, or metal, including pet food.
• Use rodent-proof garbage receptacles with tight-fitting lids inside and outside.
• Seal entry points like gaps and cracks in the foundation, soffits, around pipes, and in siding.
• Maintain your property by trimming bushes, trees, and low foliage to help reduce rodent harborage.
• Keep wood piles and other debris far from the structure.

If you suspect you have a winter rodent infestation, call for professional rodent control ASAP for effective elimination.  

Spiders 

From the common house spider to species like the bark crab spider, Rhode Island’s spider population can remain active year-round. Spiders survive cold weather by finding shelters to keep themselves and their egg sacs protected. Although they tend to be more active during warm weather, once inside, spiders seek warm, moist, dark spots where they can thrive. 

Spider Prevention Tips 

Sealing holes and cracks in your roof, siding, foundation, and around windows and doors can prevent spiders from entering. Cleaning regularly, reducing clutter, and eliminating food sources can also help minimize the risk of infestation. 

Cockroaches 

Cockroaches have been on the earth for hundreds of millions of years. They are renowned for their adaptability and resilience to many conditions, including winter’s chill. When the weather gets cold, German and American cockroaches will move into homes around New England, seeking shelter preferably in warm, moist spots. In addition to seeing live bugs, signs of cockroach activity include coffee ground-like droppings, dead cockroaches, and a musty smell. 

Cockroach Prevention Tips 

Taking a few precautionary measures can significantly enhance cockroach prevention efforts. These include: 

• Sealing gaps and cracks, particularly any in your foundation, exterior walls, and around doors and windows.
• Keeping a clean, minimally cluttered interior helps limit hiding spots and reduce potential food sources for insects.
• Avoid leaving dirty dishes in the sink or any uncovered food on counters or tables overnight.
• Regularly take the garbage out and store all food, including pet food, in sealed containers.
• Make sure there are no leaky pipes in the basement, kitchen, or bathroom areas.

Professional cockroach control is the most effective way to get rid of these creepy crawly pests and keep them away for good.  

Bed Bugs 

Bed bugs can be a nightmare in any season. These ectoparasites, which is a category of pests that live outside of their hosts, slow down a bit in winter, but they don’t hibernate. The cozy temperatures inside your home can keep bed bug populations thriving all year long. If you have warm, thick bedding, these six-legged insects can be even more difficult to discover. 

Bed bugs can hitch a ride into your home on clothing, upholstered items, and luggage. Once inside, they find dark crevices to hide away and reproduce, coming out only to feed on the blood of their hosts. Signs of bed bug activity include itchy bites, spots of blood on bedding, and dark stains along the edges of mattresses, box springs, and baseboards. 

Bed Bug Prevention Tips 

Eliminating spots for bed bugs to hide can go a long way toward reducing your chances of an infestation. Reduce clutter, invest in bed bug covers for your mattress and box spring, and routinely wash and dry your bedding. Because bed bug infestations can be notoriously challenging to eliminate on your own, it’s important to call for professional help promptly if you suspect a problem.  

Silverfish 

Silverfish are small and quite destructive. Although their size is roughly comparable to a nickel, these steel-colored insects can wreak havoc. They don’t hibernate and remain active, even in the coldest months. These insects are active at night and rarely sting people. However, silverfish consume polysaccharides, which are sugary components that are found in various objects already in your home. Book glue, furniture, artwork, carpet fibers, and wooden beams are all vulnerable. Silverfish love moist environments, which is where they typically leave their eggs.  

Silverfish Prevention Tips 

One of the ways to help prevent these moisture-loving pests from setting up shop in your home is by reducing the moisture inside. Use a dehumidifier in damp areas like basements and crawl spaces and ensure bathrooms and kitchens are well ventilated. It’s also helpful to store all the dry goods in your pantry in sealed containers and dust your home frequently. Keeping your property free of debris, including leaves and dead plants, can help ward these pests off in outdoor areas. 

Ants

Typically, ant activity decreases in winter. However, like many pests, ants spend time in autumn looking for a warm spot to take shelter from winter’s cold. If you notice ant activity indoors during winter, one of two scenarios is likely. Either you already had a colony in your home, or a colony moved in during late fall. Homeowners may see foragers or swarmers, which indicates a colony is nearby. Typically, ants build their colonies in out-of-the-way spots. Examples of places to look include under floors, inside wall cavities, inside window and door frames, and inside cabinets. 

Ant Prevention Tips 

One of the best ways to prevent ants in winter and in any season is by cutting off their food source. It helps to keep a clean home, regularly wiping the counters and sweeping up any crumbs. Avoid leaving food debris and pick up pet food once they are finished eating. With no access to food, ants often either die off or move to a new home.
